ADJUSTMENT STEP 2
Setting the Force
The force setting button is located on the back
panel of the motor unit. The force setting
measures the amount of force required to open
and close the door.
1. Locate the purple button on the back panel of unit
(Figure 1)
.
2. Push the purple button twice to enter unit into
Force Adjustment Mode
(Figure 2).
The LED
(Indicator Light) will flash quickly.
3. Push the remote control or door control
(Figure 3).
The door will travel to the DOWN (close) position.
Push the remote control or door control again, the
door will travel to the UP (open) position. Push the
remote control or door control a third time to send
the door to the DOWN (close) position.
The LED (Indicator Light) will stop flashing when the
force has been learned.
The unit has learned the forces required to open and
close your door.
The door must travel through a complete cycle, UP
and DOWN, in order for the force to be set properly.
If the unit cannot open and close your door fully,
inspect your door to insure that it is balanced
properly and is not sticking or binding.
See page 3,
“Preparing your garage door.”

Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Too much force on garage door will interfere with
proper operation of safety reversal system.
• NEVER increase force beyond minimum amount
required to close garage door.
• NEVER use force adjustments to compensate for a
binding or sticking garage door.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid
flat) on floor.
